One Plus One Equals More and four other short stories

Having read Agatha Christie as a child, I was under the misconception that mystery stories had to include a murder. They don't. Although several of these short stories do have murders, the stories run the gamut from a holiday gone wrong to a woman starting a second career as a penetration security tester. Stories include the title story, One Plus One Equals More; Saltwater; The Final Test of Maria Ramirez; Winning The Playa Real Bluffs Holiday Hop; and Of Cats and Assassins.
